The other robber is Yasue Kitamori. Yusaku and Shuichi explain that they knew this from the fact that she is not wearing a swimsuit under her outerwear, and her purchase, a pair of beach sandals. Since the other robber fell into the sea, the bank notes in the robber's wallet would be drenched and thus too suspicious to pay with. Unlike the clothes the other two suspects purchased, Yasue's sandals were cheap enough to pay for them with coins instead. Secondly, Yusaku and Shuichi noticed that Yasue's watch was stuck at 10:10. This time is what watches on display at shops are usually set to, since the handles don't obstruct the brand logos this way. All branded watches have serial numbers, so it will only take a simple comparison between Yasue's watch and the ones stolen during the robbery to prove her involvement in the crime. Yasue confesses and explains that during their escape, she and her partner got into an argument over Yasue taking the watch from the loot for herself and that this argument caused the car crash.

Conan realizes that Masumi knows that he is Shinichi Kudo, the Akai family's middle brother is Shukichi Haneda, and that their mother is Mary, now somehow shrunken.

Masumi thinks to herself that while Conan has finally remembered her, and has remembered that he made Shuichi smile and laugh when she could not, there is another reason she calls him a "wizard", a reason which he does not know.
